AbstractAbstract
[en] A full bibliography on faster-than-light particles is compiled beginning since 1889. The papers are specified in three branches: historical, experimental, and theoretical, the latter two with subsequent division. There is given a short integral analysis of the papers compiled. It shows a continuing growth of the number of publications concerning faster-than-light particles, and related topics

AbstractAbstract
[en] The author attempts to clear up the causal 'paradox' often associated with the existence of tacyons. This leads to a discussion of the nature of tachyon messages and the problems involved in their interpretation. (W.D.L.)

AbstractAbstract
[en] Tachyon paradoxes, including causality paradoxes, have persisted within tachyon theories and left little hope for the existence of observable tachyons. A way is presented to solve the causality paradoxes, along with two other paradoxes, by the introduction of an absolute frame of reference in which a tachyon effect may never precede its cause. Relativity for ordinary matter is unaffected by this, even if the tachyons couple to ordinary particles. Violations of the principle of relativity due to the absolute frame would appear only in the case of free tachyons

AbstractAbstract
[en] The boundary state corresponding to the Dp-brane with a transverse rotation in the presence of the Kalb–Ramond and tachyon background fields and a U(1) internal field will be constructed. We shall investigate effects of the open string tachyon condensation on this brane via its boundary state. We demonstrate that the background fields and transverse rotation cannot protect the brane against the collapse. Our calculations are in the context of the bosonic string theory.

AbstractAbstract
[en] In this short note we perform canonical analysis of geometrical action for Dp-brane. We also discuss tachyon condensation in case of the geometrical action for unstable D(p+1)-brane.

AbstractAbstract
[en] We derive a Kontsevich-type matrix model for the c=1 string directly from the W∞ solution of the theory. The model that we obtain is different from previous proposals, which are proven to be incorrect. Our matrix model contains the Penner and Kontsevich cases, and we study its quantum effective action. The simplicity of our model leads to an encouraging interpretation in the context of background-independent non-critical string field theory. (orig.)

AbstractAbstract
[en] It is the purpose of this paper to prove that a preferred space direction is coupled with each tachyon and, consequently, scalar tachyons, are impossible in principle. Even the notion of a scalar faster-than-light particle cannot be defined in a relativistically invariant way. (orig./HSI)
